13 Claims.

This invention relates to improvements in a printing press and is particularly applicable when employed in connection with a high speed press such as used by most metropolitan newspapers;

The principal objects of the invention are-to provide a press which operates at high speed with means contained within itself for preventing the line mist of ink which, by the action of centrifugal force, is apt to be distributed by such a press, from being thrown outside the press where it can do any damage; to provide a removable disposable absorbent or other ink retaining medium on the inside of the guards or other adjacent surfaces upon which a film of ink readily deposits from the mist thrownoff by the rollers.

Broadly the present invention relates to certain improvements pertaining to enclosures for the inking mechanism of printing presses. Safety codes require printing presses to be provided with guards and enclosures at such points where rotating rollers, cylinders and other moving parts about the printing unit would be liable to damage from entrance of foreign matter or wheresuch exposed mechanism would be likely to cause physical injury. Obviously, guards or enclosures for this purpose are necessarily in close proximity to inking rollers which run at'high speeds and throw off, due to the centrifugal action, fine particles of. ink in the form of a mist which settles and gradually accumulates on any convenient surface but more noticeably on the guards enclosingthe said inking rollers and creating as it does a troublesome problem in keeping the press reasonably clean and free from accumulation of such ink.

The primary object of the present invention I is to provide a disposable absorbent or ink retaining medium on the inside surface of such enclosing guards or other adjacent surfaces upon which a film of ink'readily deposits and is retained thereon, by absorption 'or otherwise from the mist thrown off by high speed inking rollers.

A further object of this invention is to provide means for easily removing this ink retainingmedium and replacing it with a fresh surface on which subsequent ink mist will collect.

With these and'other obvious objectives and advantages not specifically referred to, this invention consists in such novel .arrangement'as shown in the accompanying drawings but it should be understood'that variation in constructional details may be resorted to without departing from the scope of the invention.

Reference is to be had to the accompanying drawings whereincorresponding numerals of reference indicate corresponding parts in the several views. i

In the drawings Figure l is a diagrammatic end view of a printing unit provided with mechanism, shown in section, for receiving the ink absorbing material;

Figure 2 is a view in side elevation of Figure 1; Figure 3 is an enlarged detail of the mechanism shown in Figure 1 for winding the inkretaining material from one roller to the other; I l

Figure 4 is a fragmentaryview of another form of holding mechanism for the ink retaining material; i Figure 5 is a View in side elevation of Figure 4; Figure 6 is a' fragmentary side view of "the in Figure' l; I

upper portion of the holding mechanism shown Figure? is an" enlarged detail of the holding mechanism shownin-Figure 4; v a

Figure 8 is an enlarged detail of the same part shown in Figure 7 but in the holding position;

Figure 9i is a modified form of means for mounting" the ink retaining material on the guards;

Figure 10 is a-"sectional view on the line Ill-40 of Figure 9; Figure 11 is in Figure- 9. I p ll i In the drawings l indicates theink mecha nism guard or; shield provided at the upper and lower edge thereof with extensions or proj ections 2 which 'serveas bearings into which the winding reelshaft 3 and unwinding reel shaft 4 are journaled. v

"The guards l', as usual a're enclosed and surround the printing rolls and the ink retaining material 5 is unwound from the lower roll shaft 4 on to the upper roll shaft 3 on the inside of the guards I. This ink retainin'gma'terial 5 it is to beunderstoodremains in a fixed positionon the inside of the guards until it has become charged or treated with the ink mist and'is then unwound from'the lower roll shaft on tothe upper reel shaft.

The reel shafts 3 and 4 are so constructed at a top plan View of theform shown 2 spreading of same outside of the guard. A roll of any absorbent paper would be very satisfactory but blotting paper or paper such as is used in the manufacture of paper towels or newsprint could well be used. Newsprint paper is readily available in a printing plant and it would be an exceedingly simple matter to provide rolls of newsprint paper for this purpose. This newsprint paper as is well known is quite absorbent. It is, of course, possible that cloth such as burlap might be utilized as the absorbent. invention, however, is broadly to the use of any ink retaining material for this purpose and it is not intended to be restricted to any particular material provided, of course, that it will retain the ink either as a coating or by absorption. Any readily destructible, decomposable material may be utilized for the purpose.

In the use of this invention, shown particularly in Figure 1, after the ink retaining material has become coated or saturated or has absorbed the ink mist the sheet is wound up on to the upper reel from the lower reel and an entirely new surface presented for further use. After the entire lower roll has been utilized or unwound the used ink retaining material on the upper reel is removed and a fresh roll placed on the lower reel and connected with the upper reel for future use.

In the form shown in Figure 4 the upper reel is dispensed with and the sheet of absorbent or ink retaining material 5 is passed over the top of the guard l and held taut by means of a clamp bar 8 which is fulcrumed in the bearings 2 at the upper part of the guard. There is provided a spring 9 secured at one end, H), on a pin projecting from the side of the guard l and at its other end to a pin II on the clamp bar 8. This spring exents a pressure on the clamp bar so that the member sheet, after it is passed under the bar and locks the same in taut condition.

Th clamp bar is also provided with an extension l3 which may be swung to the left and hold the clamp bar open when in the position shown in Figure 8 permitting the saturated or soiled ink retaining material to be pulled out and cut oii. When the soiled material has been cut ofi from the sheet and disposed of the iresh portion is in position for receiving the mist. The guard or bar in this form is then thrown down to the position shown in Figure '7. A handle or lever 14 is formed on the clamp bar for convenience in swinging the same from locked to open position and vice versa.

In the form shown in Figures 9 and 10 the ink retaining material in sheet form is inserted in between guides l6 secured .to the inside of the guard l and when these sheets l5 become saturated or coated with ink mist they may be: readily slipped out of the guides and replaced with fresh clean sheets for further use.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent of the United States is:
